L2 resonant tuning 3 tests unloaded

voltages and current quickly rise , so will need to put L3 close coupled to L2 again, and put a resistive load on.

voltage in yellow blue is current
Note how the current jumps at the time of the impulse (Vmax positive). I think, when properly tuned, this jump can make a big difference. The "jump"  also grows in voltage(current) with rising frequency/less capacitance, but the current also grows in total...

I should keep an eye, on this "jump" and also look at changes in the phase angle between voltage and current

tuning L2, with close coupled L3 and 16.4 ohm resistive load
« Reply #101,  »Last edited
L2 and L3 close coupled.
L3 loaded with 16.4 ohm power resistors (that have some inductance).
Tuned DC input to generate -500V impulses

Did several tests, but almost no difference between them so only post the extremes:

series
cap       Fres        L2        L2      DC in    DC in
86nF   86.7kHz   76V    3.0A    0.74A    27.4V         newfile1   
116nF  84.2kHz   53V    2.8A   0.66A    26.3V         newfile2

yellow 10:1 voltage on L2
Blue 100mV/A current on L2
both probed, on the smae spot between the tuning cap and L2

Note how there are no sine waves.
L2 coil is only loaded on 1 side by L3
Note the small change in frequency with a large change in capacitance

I will need to go down in capacitance, which will mean, raising the frequency again...
I think this is a health risk, but, I'm recovered fully, and L3 coil is close coupled, and not resonant tuned, with a resistive load it will probably absorb all the energy (I hope)....

The voltage and current also don't look 90 degrees out of phase anymore. This is good! but also hard to see with these distorted waves.

Almost forgot, I can tune the impulse with the capacitance over L1.
I now use a 16.4 ohm resistance over L3. these are 2 8.2ohm power resistors in series.
But I like to have a little more current, so, I will take only one (8.2 ohm) or 2 in parallel (4.1 ohm).
The lower the resistance the higher the current...

I waited a few hours, to see how I felt. seems ok, so I will proceed with tuning L2 and see what the voltage and current do.

changed the load
from 16.4 ohm / 84.2 kHz (2 in series)
to      8.2 Ohm / 70.7khz  (single)
to       4.1 ohm/  60.9 kHz (2 in parallel)

Funny how less load drops the frequency. It has some inductance, but not much.
Maybe, the dielectric field voltage in the resistor is transformed into heat, and there for the capacitance is reduced.

Did several tests again tuning L2, with L3 close coupled, and loaded wiith the 4.1 Ohm. Again, tuned for a -500V impulse

Note how the sudden current change, at the time of the impulse (vmax positive L2), disappears at higher frequencies.
Is this a measurement error, or... not?

Also keep in mind of the phase offset of the current probe at these frequencies
OW, and yes the resistors get warm/hot. Only testing as short as possible. not leaving it running

did another test, with last setup, 46nF 85.7kHz
but measured voltage and current of L3

I know from previous tests, I need to point the arrow of the current probe pointing to ground.
But then voltage and current are out of phase (appear... phase lag not accounted) newfile 8

So I did reverse the probe, and made a screen shot of that also. (newfile9)
With the -45 phase shift, it makes more sense. but... still dont know how to probe with the current probe, with a resonant coil. Which way should the arrow point

Voltage is low, as the 4.1 Ohm resistors burns it into heat Probed with 1:1 setting yellow
and 100mV/A blue

-45 degrees phase shift @ 85 khz (see chart)

As I understand it, it is alternating current running through the coil, correct?
Then why would it matter which way you connect the current probe?
Do you get different readings is you reverse polarity on the probe?

yes phase is shifted, and artifacts are different  plus the amplitude differ.

Evo, I'd like for you to try an experiment.

This one is more about the man than the device.



Your scope depicts a two dimensional slice through the fields of your device--magnetic and dielectric.  Since you can't easily take pictures/slices at any particular location and geometric coordinates like a doctor would with an MRI machine (think brain scan), I'd like for you to engage your imagination to fill in all the blank spots you cannot see with your two eyes.  Imagination Evo, your third eye, the one we have been trained to put blinders on and forget about.

I'd like for you to imagine those fields and consider what might happen when you orient them in a manner quite different from conventional engineering.  Think about Mr. Tesla's spherical antenna where all the magnetic fields slam into each other allowing only the longitudinal dielectric fields to propagate away from the antenna.  Think about the fields produced by these flat pancake coils and how they are so much different than solenoid shaped coils.  Visualize in your mind the fields, where they are, how strong they are, what they cut through and what they reflect off of.

What I'm asking is difficult, I'm fully aware of that.  I want you to step up to the next stage of exploration.  It's time and you are ready.  What I'd like for you to do is forget about analyzing and attempting to replicate someone else's work.  I want to see your work, your creation, your imagination come to life.  Imagination is what's real; what we normally think is real is only someone else's imagination.  This is your show Evo, wow us off our feet.  Create something unique, something truly yours.  See it in your mind and make it so.

You may not comprehend what I'm asking for right at this moment, but you will.  You will soon see what very few others have.  I know you have it in you and soon you will find it.  And when you do, this will all seem like a walk in the park.

Thx Matt,
You might be right.
but I need to stop my mind. it is blocking me again.
Good thing is, I dont use black spraypaint on my third eye anymore (alcohol drugs social media).

I have a new tool that really helps.
VR
Tilt brush,
it lets me draw in 3D. really help full.
already gave me new insights.

Main thing I'm thinking about now,
Is the impulse on one end
and the regular V+ current on the other end
of the coil.

both ends feeding the resonance.
they should be able to match up.
allign, and...

I'll get there Matt.
Thanks for having confidence in me.

synchronous push and pull
« Reply #111,  »
I realized something. The L1 back emf, of - 500V 1uS is also creating pressure from the L1 coil. As one side is grounded and the other is - 500V

So by combining the pressure of L1 and L2 I can create a directed stream. one pushes, one pulls.  L3 is in between them.
Theory works. Not fine tuned yet but had 0.7A at 32V input(22W), and 28 lamp was Lit.

going to try fine tuning it later
L3 tuned in the middle
« Reply #112,  »Last edited
After some tuning, I reached the maximum brightness of the 28W halogen lamp  (not full on, but very bright).

DC input: 0.71A  32.3V  = 23W

L1 parallel tuned with 2490pF (to get a proper impulse) giving -616V impulse
L3 parallel tuned with 27nF Giving 456Vpp  and around 5,4App current, pretty much in phase.
L2 series tuned with 56nF  giving 120Vpp

At a resonant frequency of 69,525 kHz

3 Coils stacked with 15mm distance (see photo) L3 is in the middle, and L1 is reversed connected.

The max output peak wasn't that abrupt. rather a smooth build up. I kept L2 at 56nF and tuned L3 by changing with 1nF.

newfile1:
yellow=L2 10:1 voltage inside rim probed;
blue is L2 impulse outside rim probed

newfile2:
yellow=L2 10:1 voltage inside rim probed;
blue is L3 voltage inside rim probed (outside rim grounded) 10:1

! that bump at the time of the impulse, that needs to grow bigger!

newfile3:
Yellow=L3 current 100mV/A probed on inside rim;
blue is L3 voltage inside rim probed (outside rim grounded) 10:1

69,525 kHz gives a - 38 degrees phase shift on the current probe, making the blue and yellow close to in phase.

Note how L2 is only 120V peak to peak, and L3 is 456V peak to peak, while being loaded with the 28W lamp!
L3 being in the middle is coupled to L1 and L2.

The trick seems to be, L1 back emf=impulse negative pressure
 L2 impulse with resonant sine, gives a polarity change in L2, creating positive pressure.
negative, flows towards positive, and this is the condition to create a ring toroid.

Notice, how the voltage grows at the time of the impulse.

I feel this isn't the proper setup yet. Want to try with L2 in the middle. if its the same, I will need to progress to a double system

Also working on new video material.

L2 in the middle
« Reply #113,  »
with L2 in the middle, the same effect is observed. L3 now is only coupled on one side, so it will need to be retuned to see the full effect. then Ill know how low the DC input current drops. and how high the output rises
SiC
« Reply #114,  »
I tried a 2m0160120d cree/wolfspeed mosfet,
1200V 160mOhm
 but It needed more current, and gave less impulse.
I guess, because I use 15V for the gate, and it need 20V for best performance.
Could tweak it, but will save it for the future.

I intended to inject a higher negative voltage impulse, from the back emf of L1.
But I'm already at 32V  I could switch my powersupply  in series and get 64V. but...
expierence showed, the impulse needs tuning, If I make it faster It wont always make a single impulse, but it starts to ripple
Re: advancing the Solid state Tesla hairpin circuit
« Reply #115,  »
I need to see If I can increase this bump, seen on L2 and L3

If L3 isn't tuned (no parallel cap over L3), does it still show up on L2?
If so, L2 could be tuned, to get a maximum bump

yellow=L2 voltage 10:1
blue=L3  voltage  10:1

bump
« Reply #116,  »
I replaced the lamp and caps on L3, with a 4.1 ohm resistor, and looked If I still could see the bump on L2.
And yes its there. Now I can see if tuning L2, has an effect on that bump.

43.64 kHz
L2=540Vpp (yellow 10:1) impulse is -610V (blue 10:1)

Re: advancing the Solid state Tesla hairpin circuit

I stepped up the series capacity of L2 with 10nF steps to 106nF
I didn't really see a difference in the bump. it  did gain some volts from 18 to 34V
but nothing dramatically.

I need to do an analysis and understand what it is. Where does this voltage come from?

the impulse on the other side of L2 is negative, So the relative voltage over L2 is changing polarity.
During the impulse it first neutralizes the voltage difference, but the impulse is always more negative then the resonant sine is negative.

So the negative resonant part becomes relatively positive to the impulse.

At that point in time there is no magnetic field, so the Aether is free moving.

is it "closing the gap"  by becoming more negative, that is relative less positive?

I really want to test again with a smaller L2 resonamt voltage. during the tests I used 4.1 ohm that quickly became searing hot.
If I increase the resistance, the amps will be lower, and thus the voltage also? this could make L2 lower in voltage, giving a bigger delta V between its ends.

Or make the impulse bigger, but that would need a tweaked gate driver, giving 20V.

edit: a bigger resistor is a smaller load... right? Don't I need a smaller resistor to get the voltage down... small resistor, high current and voltage, taken way from L2 reducing its voltage?
sometimes.... no often, logic fails me. And that's a good thing
capacitor tuning switchboard
« Reply #118,  »Last edited
I had enough (10) switches to make a capacitor switch board.
this way I can more easily tune. by connecting 1nF to each switch.

they are not fully rated for the voltages, but I guess I will be fine.

once I reach 10, I ad another 10nF, reset the switches and proceed

need some more switches for the 10nF caps.

tested it and it works.
this makes tuning so much easier!

High Q
« Reply #119,  »
while playing I saw a flash in the lightbulb.
could not zoom into the frequency.

after thinking it over, I realized I made coils with relative high inductance / capacitance and low resistance.

This means the Q is very high. And when I'm tuning, O need smaller steps. 1nF is to big.

I ordered more switches so I can include a row of 100pF and make small adjustments in the resonant frequency.
Re: advancing the Solid state Tesla hairpin circuit
« Reply #120,  »Last edited
still waiting on the switches for the tuning board.
Meanwhile, close coupled L1 and L2, gives more reduced current consumption, while still giving a big impulse over L2. L3 on top 15mm distanced, untuned, with a 28W lamp, made it glow orange. This is good... This needs parallel tuning...
then mirror the same setup (another l1 amd l2 bit out of phase) on the other side of the L3 coil.

I realized, that the delta V/ delta T  is basically the amount of current, as Steinmetz explained. making delta V big and delta T small, (impulse) is basically creating a current spike.

Current, is an indicator for the magnetic field, but, if the current spikes, the inertia of the (dense) Aether, creates a ring torroid, under the right conditions.

A ring torroid, has polarity, in its turning direction.

the longitudinal pressure needs to be given a direction.
This is done by creating 2 impulses, one pulling and the other pushing, one positive, the other negative.

The L1 has a collapsing magnetic field, creating an impulse over L1, thus it generates pressure.

L2 has the impulse over it, at the same time, and also creates pressure, as the impulse is timed when the magnetic field is zero (V max negative, series resonant). but it has " opposite"  pressure

the system is resonant, so the ring toroid grows and shrinks, reverses direction and grows and shrinks again, making one period.
The 2 systems create 2 ring vortices, that are joined into 1, around L3 in the middle.
This is a high precision setup... Tuning is key. not only by L3 capacitance, but also in distance, and equal coils, mass etc...

At present the phenomenon is described as follows: When a high voltage is established between the electrodes of an asymmetric capacitor, a net force is observed on said capacitor. We will understand an asymmetric capacitor, that in which the physical dimensions of both plates are very different. Based on this phenomenon it is possible to build prototypes in which the force originated exceeds its weight, such as the one presented in this communication and others that can be found on the internet [7]. It is observed that there always appears a force directed towards the small electrode and that said force appears independently of the sign of the DC voltage used.

388/5000
In this video, the coil is powered by a Halogen focus ELECTRONIC transformer that provides 12 V at about 44 kHz (actually the voltage given by this type of transformers is the 50 Hz signal chopped at about 42-44 kHz, depending of the model). This allows to levitate coils of few turns, because at those frequencies their inductance is much greater than the resistance.
